===== 10.2 Security Violations ===== The Java Card RE throws a **java.lang.SecurityException** exception when it detects an attempt to illegally access an object belonging to another applet across the firewall boundary. A **java.lang.SecurityException** exception may optionally be thrown by a Java Card VM implementation to indicate a violation of fundamental language restrictions, such as attempting to invoke a private method in another class. For security reasons, the Java Card RE implementation may mute the card instead of throwing the exception object. Copyright © 2005, Sun Microsystems, Inc. All Rights Reserved.
